FORM is a Symbolic Manipulation System. It reads symbolic expressions from files
and executes symbolic/algebraic transformations upon them. The answers are
returned in a textual mathematical representation. As its landmark feature, the
size of the considered expressions in FORM is only limited by the available
disk space and not by the available RAM.

A Common Data Frame Format for Interferometric Gravitational Wave Detector has
been developed by VIRGO and LIGO. The Frame Library is a software in C
language, with interfaces to python and matlab, dedicated to frame data
manipulation including file input/output.

mode for use by GEANT4.

Data files for low energy electromagnetic processes are derived from
the Livermore data libraries (except for the photoelectric_angular
module):
* EPDL97 - Evaluated Photon Data Library
* EEDL - Evaluated Electron Data Library
* EADL - Evaluated Atom Data Library
The data have been reformatted for usage in Geant4 and some files
contain values resulting from fitting of the original data.

This package provides a data set of nuclides state properties derived
from the Evaluated Nuclear Structure Data File for use by GEANT4.

This package provides a data set of proton and neutron density profiles in INCL
for use by GEANT4.

This package provides neutron data files with thermal cross-sections
for use with GEANT4.

Neutron cross-sections and final states are obtained from Joint
Evaluated Fission and Fusion File (JEFF version 3.3). Files not
coming from JEFF-3.3 and corresponding to previous G4NDL versions are:
JENDL_HE, IsotopeProduction, ThermalScattering, Inelastic/Gammas,
Fission/FF. Information concerning the conversion process of JEFF-3.3
to the G4NDL format can be found in: E.Mendoza and D.Cano-Ott, IAEA
technical report INDC(NDS)-0758, Vienna, 2018.

Evaluated data produced using data sets via averaging procedure for neutron energies.

This package provide data files for photon evaporation for use by
GEANT4. Photon evaporation data comes from the Evaluated Nuclear
Structure Data File (ENSDF) which is maintained by the National
Nuclear Data Center, Brookhaven National Laboratory.

This package provides a data set of shell ionisation cross-sections for use by
GEANT4.

This package provide data files for radioactive decay hadronic processes for
use by GEANT4. The radioactive decay data comes from the Evaluated Nuclear
Structure Data File (ENSDF) which is maintained by the National Nuclear Data
Center, Brookhaven National Laboratory.

This package provides a data set of measured optical surface reflectance for
use by GEANT4.

This package provides data files from evaluated cross-sections in SAID
data-base for use with geant4.

This package provides data files for incident particles for the simulation of
nuclear reactions.

GluCat is a library of template classes which model the universal Clifford algebras over the field of real numbers, with arbitrary dimension and arbitrary signature. GluCat implements a model of each Clifford algebra corresponding to each non-degenerate quadratic form up to a maximum number of dimensions.

Gri is a language for scientific graphics programming. It is a
command-driven application, as opposed to a click/point application.
It is analogous to latex, and shares the property that extensive power
is the reward for tolerating a modest learning curve. Gri output is
in industry-standard PostScript, suitable for incorporation in
documents prepared by various text processors.

Gri can make x-y graphs, contour-graphs, and image graphs. In
addition to high-level capabilities, it has enough low-level
capabilities to allow users to achieve a high degree of customization.
Precise control is extended to all aspects of drawing, including
line-widths, colors, and fonts. Text includes a subset of the tex
language, so that it is easy to incorporate Greek letters and
mathematical symbols in labels.

The HDF project involves the development and support of software and
file formats for scientific data management. The HDF software includes
I/O libraries and tools for analyzing, visualizing, and converting
scientific data.

The HepMC package is an object oriented event record written in C++ for High Energy Physics Monte Carlo Generators. Many extensions from HEPEVT, the Fortran HEP standard, are supported: the number of entries is unlimited, spin density matrices can be stored with each vertex, flow patterns (such as color) can be stored and traced, integers representing random number generator states can be stored, and an arbitrary number of event weights can be included. Particles and vertices are kept separate in a graph structure, physically similar to a physics event. The added information supports the modularisation of event generators. The package has been kept as simple as possible with minimal internal/external dependencies. Event information is accessed by means of iterators supplied with the package.

Herwig is a multi-purpose particle physics event generator. It is built based on the experience gained with both the HERWIG 6 and Herwig++ 2 event generators. Continuing the Herwig++ 2 development, Herwig 7.0 (Herwig++ 3.0) replaces any prior HERWIG or Herwig++ versions.

Herwig provides significantly improved and extended physics capabilities when compared to both its predecessors, HERWIG 6 and Herwig++ 2, while keeping the key model motivations such as coherent parton showers (including angular-ordered and dipole-based evolution), the cluster hadronization model, an eikonal multiple-interaction model, highly flexible BSM capabilities and improved perturbative input using next-to-leading order QCD.

Herwig is based on ThePEG.
